Deny the attacker’s path
Harness the power of identity-based deny. Control and segment access to every resource and block malicious access attempts in real time.
- Deploy with no code changes.
- Contain active threats in real time.
- Enforce least-privilege policies.

Your access controls are not airtight.
Traditional access policies leave blind spots. Once attackers compromise a user or system, they can often move laterally, escalate privileges, exploit weak protocols, or abuse misconfigurations to expand access.

From fragmented policies to powerful defense
Silverfort Authentication Firewall gives you full control over authentication and access across every environment. By enforcing granular deny and segmentation policies inline at the protocol level, including local account authentications, it prevents lateral movement and unauthorized access—no agents, no app changes, no workflow disruption.
Full access segmentation
Enforce granular, least-privilege policies to control access across every system and user group.
Real-time deny & containment
Reduce blast radius and stop ransomware from spreading by blocking risky access attempts and lateral movement instantly.
Fast, non-disruptive deployment
Integrate directly into your IAM infrastructure for rapid rollout—even during incident response—without app changes or workflow impact.

How Silverfort boosts your environment’s resilience with the power of deny.
From siloed controls to centralized enforcement—dynamic, automated, unstoppable. Silverfort prevents lateral movement and unauthorized access by challenging or denying risky authentication attempts and dividing your environment into logical access segments, stopping attackers before they can move or escalate.
Protect every resource—even those you couldn't before
Apply access policies to any system, in any environment, without deploying proxies or agents.
Silverfort connects directly to your identity infrastructure, extending enforcement to every AD-managed resource, and even local account logins on Windows endpoints that couldn’t be protected before. No architectural rewiring.
Block non-legitimate access in real time
Detect and stop suspicious activity the moment it happens—and before it spreads.
Silverfort continuously monitors authentication requests across your environment and enforces policy in real time. Access can be challenged or blocked instantly based on risk, behavior, and context—including insecure or misconfigured protocols like NTLM—all without needing endpoint agents or network changes.
Segment access without network complexity
Divide your environment by access logic.
Silverfort enforces identity-based segmentation by limiting each identity to only the systems it should access. This stops attackers from jumping between systems, even when the network is flat or unmanaged. Its segmentation built for identity-first environments – fast to deploy, with no user friction.
Contain active threats and boost IR with access control
Turn access policies into a real-time incident response lever.
During an attack or investigation, Silverfort enables you to dynamically restrict, isolate, or cut off access across all affected identities, systems, and protocols. Security teams can respond instantly and surgically, without waiting for network changes or endpoint lockdowns. One-click deny policies deliver rapid containment, stopping malicious access in its tracks.

Silverfort is the only solution that can prevent ransomware attacks by enforcing protection on the access tools that these attacks use to propagate in the network.
